Like suji, other waits - specifically, waits that are not sequences - are still possible. It is also possible to target 3 or 7 with a [[penchan]]. Overall, kabe is comparable to suji (though kabe is safer), and should be used in a similar fashion.

===Sotogawa===
{{main|Sotogawa}}
Sotogawa states that, when a tile is discarded early (generally within the first 6 discards ''and'' not the [[riichi]] declaration tile), tiles further from 5 become safer. For example, a discarded 3-sou means that 1-sou and 2-sou are safer.
It works because players are unlikely to discard a 3 from a "233" or "334" shape early. Therefore, if 3 is discarded, it is less likely for an opponent to have a "23" or "34" remaining. Since "23 and "34" wait on 1-4 and 2-5, both 1 and 2 are safer. 4 and 5 are not much safer as an opponent could still have a "56" or "67" ryanmen.

** [[Ukeire|Tile acceptance]] / [[wait]]s at tenpai: It's much better to attack if you have good waits (wait with >= 6 tiles remaining). Similarly, at 1-shanten, it's best to have strong tile acceptance.

* [[Situational analysis]]: Especially when close to [[oorasu|all last]], consider what happens if you win, if you deal in, and if an opponent tsumos. For example: if it's all last, 4th place declares [[riichi]], and you are 3rd with only a 1000 point lead, you dealing in and having opponent tsumo would both result in you ending in 4th. Therefore, you would be forced to attack.

* Turn count (Number of safe tile types available): As more tile types become safe, the more dangerous the other tiles become (see [[Suji#Suji counting|Suji counting]] for more detials). Therefore, as the game progresses, you should be more willing to fold. The longer the game goes on, the more safe tiles are revealed, and thus the more dangerous it is to push.
